anomalous dispersion glassとは 意味・読み方・使い方

A positive lens 1 made of anomalous dispersion glass and a negative lens 2 made of synthetic quartz are assembled in a lens frame 4 and fixed by a lens pressing member 5.例文帳に追加

異常分散硝子製正レンズ１と、合成石英から成る負レンズ２とをレンズ枠４に組み込んでレンズ押え５で固定する。 - 特許庁

To provide optical glass which corrects the chromatic aberration of a glass lens with high accuracy because of its higher anomalous dispersion, which has a high refractive index and low dispersivity, and is excellent in devitrification resistance, and to provide an optical element and a preform.例文帳に追加

異常分散性がより高いことでガラスレンズの色収差を高精度に補正することができ、さらに高屈折率、低分散性を備え、加えて、耐失透に優れる光学ガラス、光学素子およびプリフォームの提供。 - 特許庁

To provide a telephotographic lens capable of realizing a reduction in cost and a reduction in weight by drastically reducing the number of pieces of anomalous dispersion glass to be used while excellently correcting chromatic aberration.例文帳に追加

色収差を良好に補正しつつ、異常分散性ガラスの使用枚数を大幅に低減して安価・軽量化を実現することが可能な構成の望遠レンズを提供する。 - 特許庁

To provide optical glass which corrects the chromatic aberration of a glass lens with a high precision because it has high anomalous dispersion, has a high refractive index, a low dispersion (high Abbe's number), and an abrasion equal to or lower than that of a conventional one, and thereby is easily subjected to polishing, and to provide an optical element and a preform.例文帳に追加

異常分散性がより高いことでガラスレンズの色収差を高精度に補正することができ、さらに高屈折率、低分散性（高アッベ数）を備え、加えて、従来のものと同等以上に摩耗度が低く研磨加工を行い易い光学ガラス、光学素子およびプリフォームの提供。 - 特許庁
